Keylor Navas' signing could finish the dual keeper system at Real Madrid

It's old news now. Keylor Navas has joined Los Blancos for a fee of around 10 million Euros. The question now becomes, what happens to Lopez and Casillas?

There is no easy answer. Casillas has shown a significant decline in his goalkeeping ability over the past year. Whether this is a result of his inevitable aging or his intermittent time between the sticks seems to be the most crucial question.He most certainly was not at his best during the World Cup, an observation made more painfully obvious by Spain's expeditious exit. But what is to be considered his best anymore?

Does Casillas have what it takes to remain in goal for the Ten Time European Champions? it is unclear, but the answer, much to the chagrin of long-time Madridistas, seems to be in the negative.

Diego Lopez, on the other hand, has demonstrated astounding ability and value. He has also reiterated in the press time and again that he has no desire to leave the Bernabeu despite Navas' arrival. This is sure to give Ancelotti one doozy of a selection headache.

Navas wowed everyone with his performances in Brazil, and was a fundamental part of Costa Rica's long thrust into the latter stages of the World Cup. With the recently announced acquisition of Toni Kroos, and the seemingly inevitable purchase of James Rodriguez, it looks like Los Blancos have had the pick of the litter with regard to stars from the World Cup.

In light of all this, we will definitely be keeping our eyes on Valdebebas and the pre-season friendlies to see who will be tasked with protecting our goal in the 2014 season.
